\\ Pari/GP code for working with elliptic curve 5.5.24217.1-85.2-b2

\\ (Note that not all these functions may be available, and some may take a long time to execute.)

\\ Define the base number field: 
K = nfinit(Polrev([1, 3, -1, -5, 0, 1]));

\\ Define the curve: 
E = ellinit([Polrev([2,4,-4,-1,1]),Polrev([-6,-3,14,1,-3]),Polrev([2,4,-4,-1,1]),Polrev([-103,-74,232,26,-50]),Polrev([225,-4,-330,-10,65])], K);

\\ Compute the conductor: 
ellglobalred(E)[1]

\\ Compute the norm of the conductor: 
idealnorm(ellglobalred(E)[1])

\\ Compute the discriminant: 
E.disc

\\ Compute the norm of the discriminant: 
norm(E.disc)

\\ Compute the j-invariant: 
E.j

\\ Compute the torsion subgroup: 
T = elltors(E); T[2]

\\ Compute the order of the torsion subgroup: 
T[1]

\\ Compute the generators of the torsion subgroup: 
T[3]
